“…Chronic renal failure (CRF) and dialysis treatment have been confirmed to affect the central nervous system and neurocognitive function [18]. PM is collated with various areas of the brain as a significant component of memory [19]. In addition, compared to RM, PM is explained more in terms of day-to-day memory functioning, which is required in self-care, self-management and monitoring.…”

“…Memory is one of the important cognitive functions for human, which could be divided into retrospective memory (RM) and PM, [16] and different types of memory involve different region of the brain. [17] Complaints of memory decline are perhaps the most frequently reported cognitive difficulties in breast cancer survivors, which historically has been the exclusive focus of objective memory. PM is one of the most important forms of human memory.…”

To investigate the relationship between depression and the self-reported prospective memory (SPM) problems in breast cancer survivors who have received chemotherapy. Sixty-three breast cancer patients were administered with self-rating depression scale (SDS) and the prospective memory questionnaire as part of extensive neuropsychological assessments before and after chemotherapy. The performance of SDS and SPM were compared, with the level of significance set at P < .05. Compared with the group before chemotherapy, there is a significant difference on the SPM score ( t = 6.069, P = .000) in breast cancer patients after chemotherapy. Further, there is also a significant difference on the SPM score ( t = −4.348, P = .000) between the patients with and without depression group after chemotherapy. The present result indicated that the depression in breast cancer survivors after chemotherapy may be involved in their chemotherapy-induced SPM impairment.

“…In the present study, DE, MSE, and PE were computed in terms of the brain variability across distributed regions. This approach was motivated by the findings that underlined the distributed nature of the brain function [57][58][59][60]. For instance, prior research indicated that most accurate neural signature of discrete emotions were associated with the brain's anatomically distributed variational patterns [61].…”

As alternative entropy estimators, multiscale entropy (MSE) and permutation entropy (PE) are utilized for quantification of the brain function and its signal variability. In this context, their applications are primarily focused on two specific domains: (1) the effect of brain pathology on its function (2) the study of altered states of consciousness. As a result, there is a paucity of research on applicability of these measures in more naturalistic scenarios. In addition, the utility of these measures for quantification of the brain function and with respect to its signal entropy is not well studied. These shortcomings limit the interpretability of the measures when used for quantification of the brain signal entropy. The present study addresses these limitations by comparing MSE and PE with entropy of human subjects’ EEG recordings, who watched short movie clips with negative, neutral, and positive content. The contribution of the present study is threefold. First, it identifies a significant anti-correlation between MSE and entropy. In this regard, it also verifies that such an anti-correlation is stronger in the case of negative rather than positive or neutral affects. Second, it finds that MSE significantly differentiates between these three affective states. Third, it observes that the use of PE does not warrant such significant differences. These results highlight the level of association between brain’s entropy in response to affective stimuli on the one hand and its quantification in terms of MSE and PE on the other hand. This, in turn, allows for more informed conclusions on the utility of MSE and PE for the study and analysis of the brain signal variability in naturalistic scenarios.
